Camera Controls
The SSASC camera settings will ini- tially be set to factory default values.
All camera features are controlled via remote control and the OSD menu (On Screen Display). Selections are made using the navigational Menu buttons (up/down/left/right) and select button (center) of the remote control (Figure 4).
Pressing the center button for a short period of time will bring up the OSD menu (Figure 5).
WHITE BAL. (white balance).
CCD security cameras feature this adjustment to compensate for ambient light color. Since there’s a color differ- ence between standard light bulb light and sunlight, white balance adjusts to ensure a more realistic picture.

Automatic Light Control (ALC) indi- cates the image sensor’s ability to automatically adjust in diverse lighting
conditions to yield the most vivid video Figure 6. ALC Shutter speed menu. image possible (Figure 6. Shutter
speeds can be selected for different lighting conditions.
For the optimum results at night SHUTTER should be turned OFF.
AES – Auto Electronic Shutter
AES is used when a manual or fixed iris lens is fitted and the shutter speed will respond to the amount of light to keep the signal output at optimum level. AES allows changing the iris level automatically without using the auto iris lens.
Note: The AES should be switched off when an Auto Iris Lens is fitted hence AES is not used in this application.
There are two white balance control modes, namely Auto tracking white balance (ATW) and Auto White Balance (AWB).
AWB – Auto White Balance
AWB is a preset type function whereby white color in the scene is detected and white balance is automatically adjusted, then the setting status is stored. It auto- matically memorizes the adjusted white balance value every time the AWB is selected. AWB is most suitable for environment with little change in light source.
ATW – Auto Tracking Balance NARROW (darkness adjustment) WIDE (Light adjustment)
ATW functions by detecting white color in the scene at a color temperature from 3200 to 10000 Kelvin. The color temperature is being monitored continuously and the white balance is set automatically by internal controller.
ATW is most suitable for viewing objects with changing color temperature and which can make the picture color look more natural. This mode is also helpful in light polluted skies.
FLC – Flickerless mode
ON or OFF
Flickerless mode is used for suppressing the flicker of light (illuminating the cap- tured scene) produced depending upon the frequency of the power source. In 50Hz area, the CCD exposure time is 1/50sec and if NTSC camera is used with working frequency of 60Hz, there will be flicker on the screen. Same will happen in using PAL camera in a 60Hz area. The shutter speed is fixed to 1/100 sec for the 50 Hz area and 1/120 sec for the 60 Hz area to reduce the flicker of the fluo- rescent light.
Note: FLC is normally set to ON.
AGC – Automatic GAIN Control
ON or OFF
The AGC function provides a clear image in low light condition. This controls an amplifier that is used to boost the video signal when the light dims so as to increase the camera’s sensitivity.
